| Maintenance Cost | Hoch (frequent seal replacement) | Niedrig (service life only 6 months) | Maintenance-free, life >5 Jahre |
| Sterilization | Not autoclavable | Deforms & fails sterilization | Withstands >1000 autoclaving cycles |
Core Advantages of Alumina Ceramic Valve
Medical-Grade Safety & Sauberkeit
- Biocompatibility certified: ISO 10993-5 cytotoxicity test, USP Class VI, safe for long-term blood contact.
- Anti-protein / blood cell adsorption: surface energy < 30mN/m, reduces biofilm formation, lowers cross-contamination, cleaning efficiency +50%.
High-Precision Separation Control
- Nano-scale flow channel machining: flow path tolerance ±0.01mm, separation accuracy ±1μL, CV < 2%, meets CLIA standards.
- Anti-coagulation design: laser micro-textured inner wall (Φ0.1mm), inhibits platelet aggregation, prevents thrombus blockage.
Extreme Haltbarkeit
- Corrosion resistant & maintenance-free: withstands blood, saline, hypochlorous acid disinfectant; service life 10× stainless steel valves, no lubrication needed.
- Autoclavable: withstands 134°C autoclaving (>1000 cycles), suitable for reusable medical devices.
